But look, you don't HAVE to watch this. You don't. You really don't. It might trigger some goodness for some of you, but none of you, at all, have to watch this gameplay.
I mean, really, if you don't watch it, probably no harm. But if you do, you might get it. You should play Stanley Parable, too. So you can understand the yellow line on the map (yellow in IV, a key aspect).
One key from one game opens a door in a completely separate game. A key isn't always for a door, though.
How long will it take? We'll probably all be dead by the time "this" works. By the time "we" are all free, "we" will all be dead, and only "they" will be free. "lol".
